To all whomt't may concern Be it known that I,'THo P'soN W; Bnao i, asubject of the King of, Great Britain, residing at Milwaukee, in thecounty of Milwaukee and State of WVisconsin, have invented certain newand useful Improvements-in Methods or Processes of Producing Mosaics,

f of which the following is a specificatiomreference beinghad to theaccompanying drawing, forming a partithereof.

This invention relates to mosaics for orna-- mental. and buildingpurposes and the objects of the invention are to produce such and thelabor required to'setthe blocks or or pieces of mosaic work have to bepieces'inthe base or hinder, such labor being performed manually. Manual'labor is expensive and slow especially where the blocks separatelyembedded in a base or binder. Moreover, it is diflicult to securely andfirmly set the blocks or pieces in the binder or base by hand so thatthe binder sticks to all thelem; bedded parts of the blocks or pieces, Q

Myinvention overcomes the present difficulties in this'art because timeand labor are reduced to the minimum. The blocks or pieces require nopreliminary shaping nor any manual placing. Pieces of material, such asmarble, for example,if obtainable of approximately the desi'redsizes canbe used without any preparation Whatever. Ordinarily, however, in actualmanufacture, it

will be foundto bechea'per, as well as actually necessary, to crush thematerial obtain able in a rock crusher of some suitable kind toapproximately the size it is desired to use, and the roughness orirregularities of the surfaces of the blocks or pieces does not matterfor reasons to be presently explained.

The gist of my invention consists in moldnn or casting the blocks orpieces, mixed throughoutthebody of a suitable binder, in suitable moldsor forms and then cutting or sawing through "the conglomerate mass so.formed to provide the substantially smooth, exposed surface. of'the-1nosaic, which may then be polished, if desired, in any preferredunanner,

Referring to the drawings w pany' this specification and form a parthere of, Figure 1. is a diagrammatic illustration, inperspective, of amolded or cast mass of my conglomerate mosaic material showing how sucha mass may be sawed into" slabs, for example; Fig. 2 is a perspectiveview of a part of a slab sawed or cut from a mass such as that shown byFig. 1, forexample;

the possibilities of adaptation of theinvention; Fig. 4 is a perspectiveview of a part of a slab out from the mass illustrated by Fig. 3 andFig. 5.is a perspectiveview of a :mold. l I In the manufacture of mymosaic, marble or other suitable material or materials may 3 be crushedin a stone crusher and the crushed material may thenbe mixed with anysuitable binder as, for example, cement. and water, in a concrete mixer.ing batch of conglomerate may then be poured into a suitable form ormold to .setand after it is sufiiciently hardened it may,

to more completely or to completely harden. The next step in the processis to out or saw the molded mass so as to cut into or through both thebinder and the pieces of marble, or other. material or materials,embedded there in so as to produce a mosaic surface. Any pitting of thesurface caused by'the cutting or sawing'can then be smoothed with cementOn the drawings, the reference numeral 1 designates a molded or castmass of the con glomerate which has been subdivided by saw cuts 2 intoslabs 8, The reference numeral 4- designates the binder and 5 the piecesof marble, or other material or materials, embedded in the binder.

The front face of the part of the slab shown by Fig. 2- shows thecompleted Inosaic;

The binder may be colored in any selected manner and the pieces embeddedtherein may be of the same or ofdifferent colors.

if desired, be removed from'the form ormold Fig. 3 is a View similar toFig. 1 illustrating The resultor binding material and the surfacepolished.

Figured effects may be readily obtained by placing in the mold or formfor the mass supplemental forms or molds and filling the supplementalmolds with mosaic material ofcontrasting appearance as compared with thebody of the mosaic. Preferably this result is accomplished by using thinmetal molds or forms, open at the ends, as

shown by Fig. 5 of the drawings, of the cross sectional shape of thefigured eflect desired. The form or mold is filled with the mosaicmaterial and. the supplemental forms or molds are filled withcontrasting mosaic material and then the supplemental forms or molds arewithdrawn before-the;

binder sets so that the different parts of the mass join together toform a single mass.

- If desired the supplemental molds or forms may be left embedded in themass instead of being withdrawn.

Fig. 3 of the drawings illustrates a mass of mosaicfsimilar to thatshown by Fig. 1

except contrasting material has been moldedinthe mass by supplementalmolds like that illustrated by Fig. 5 of the drawings. Fig.

4 of'the drawings shows clearly how the contrasting material runsthrough 'a slab and the mass in the selected figured shape.

By mixing the blocks or pieces with the binder they are thoroughlyincorporated and mixed with the binder so that they are firmly cementedin position thereby not only producing a solid mass but also insuringagainst their being torn out of the binder while the cutter orfsaw is atwork on them.

While for simplicity bf illustration I have shown merely masses'of theconglomerate andslabs out therefrom, it should be undercut into thepieces embeddedxin' the binder stood that the. conglomerate may bemolded in any form desired and'then so much of.

the surface or surfaces cut or sawed to to produce the mosaic surfacedesired The mere molding is net suflicient to produce the desiredresults because sufficient area of embedded pieces would not show aswill be "readily understood but the part to be cut or sawed ofl toobtain the desired surface effect will depend on the character of themolded mass and may be little or much and may become waste or not. Inthe drawings I have illustrated a method of obtaining slabs with littlewaste.

. The mosaic produced by this method is a very strikingand handsomematerial which can be used for all ornamental and building 2. The methodor process of producing mosaic which consists in mixing pieces ofmaterial throughout the body of a binder,

molding the conglomerate mass thus ob-' tained, allowing the mass toharden and then forming a surface by cutting through the binder and thepieces embedded therein.-

3. The method or process of producing ,mosaic which consists in mixingcontrasting masses each composed ofpieces of material mixedthroughout-the body of a binder, molding the contrasting masses into adesign, and forming a surface by cutting through .the binder and thepieces embedded therein in a plane intersecting thedivision between thecontrasting masses.
